Barbecued chicken marinated in honey and lemon

To make the marinade: pour the honey into a small saucepan, add the preserved lemon and bring to the boil. Cool to room temperature, then stir through the lemon thyme. Pour over the chicken and marinate for at least two hours - or overnight - in the fridge. Barbecue or grill the chicken until cooked through. Serve on a bed of rocket or watercress (optional).
